You can use the fields in MAPFLD for QRYSLT without specifying FORMAT
(ie. FORMAT is *FILE).

   OVRDBF  HTURISM SHARE(*YES)                                      
   OPNQRYF HTURISM QRYSLT('MPYM=%RANGE('|<&FM_YYM|>&TO_YYM|<')') +  
           OPTION(*ALL) MAPFLD((MPYM 'YY*100 + MM' *ZONED 6 0))     

But, I have never used it in the KEYFLD before. So I tried to use it,
and I knew something. You should use it with FORMAT file.

       1700 - OVRDBF FILE(MBRV1LP) SHARE(*YES)                               
       1800 - OPNQRYF FILE((MBRV1LP)) KEYFLD((*MAPFLD/USR)) MAPFLD((USR      
       '%SST(W6USID  1 5)' *CHAR 5))                                         
     Key field *MAPFLD/USR not valid for record format. <CPD3112> 
     Error occurred during processing of command.                            
       2200 - RETURN                                                         

So, I made the MBRV1LP2 that had a 'USR' field (*char 5) That was
defined in MAPFLD. And I specified FORMAT(MBRV1LP2).

       1700 - OVRDBF FILE(MBRV1LP) SHARE(*YES)                                
       1800 - OPNQRYF FILE((MBRV1LP)) FORMAT(MBRV1LP2) KEYFLD((*MAPFLD/USR))  
       MAPFLD((USR '%SST(W6USID  1 5)' *CHAR 5))                              
     Member MBRV1LP file MBRV1LP in MBRDBF opened.                            
       2200 - RETURN                                                          

After it was opened, I copied it to the real file MBRV1LP2 by CPYFRMQRYF.
(You don't need OVRDBF...SHARE(*YES) when you use CPYFRMQRYF.)

Of course you can make some RPG programs that refer to the virtual file
arranged by OPNQRYF (You need OVRDBF...SHARE(*YES) in this case.)

Oh, I noticed you said ,'but that wouldn't - compile -.' Did you mean
that you could not succeed in the CRTCLPGM?
